Decode cassandra thrift message with PHP and tcpdump

  1. Capture some data using tcpdump:

    tcpdump -enx -w cassandra-dump port 9160

  2. Open the file with wireshark and find a packet where the data looks related to casandra e.g. it has multiget_slice or similar commands near the start of the data.

  3. In wireshark select the data part of the packet and right click -> copy -> bytes -> hex stream

  4. Now you need a thrift library to decode the data. thobbs/phpcassa should work.

Cassandra Useful Commands
# Show the latency across keyspaces
nodetool cfstats | grep "Latency"
# Identify how many replicas have a row
# 1. use cassandra-cli to identify row key (connect <host>/<port>; use <keyspace>; list <table> limit 1;)
# 2. copy key into: nodetool getendpoints -- <keyspace> <table> <key>
#Node Exceptions
nodetool info | grep Exceptions
